a certain area continuously, as the feature of LCD TV panel.

Once Image retention occurs, change the mode into Video mode which displays more motion
pictures. It will help reduce this matter, but cannot completely eliminate once it occurs.
It makes the screen’s brightness worse as displaying a fixed pattern often.

manufacturer.

come under the warranty.
